Energy identification codes

The purpose of the Energy Identification Coding (EIC) Scheme is to provide a standardised codification scheme for identification of the components of power systems (both electric power and gas) and market participants. The EIC system is established in order to facilitate data exchange processes between a power system and market participants on a national and European scale. 

EIC coding scheme has been established by the European Network of Transmission System Operators (ENTSO-E) upon request of the European Commission. ENTSO-E is also nominated as the EIC Central issuing authority (EIC CIO). The tasks of EIC CIO include development and supervision of code management processes, maintenance of a register of European scale, as well as nomination of the local issuing authorities (EIC LIO). EIC LIO is responsible for maintenance of the national register and organization of the national management processes (including issuing and deactivisation of codes) according to the guidelines developed by ENTSO-E.

AS “Augstsprieguma tīkls” is the nominated EIC LIO in the Latvian electric power market and AS "Conexus Baltic Grid" is the nominated EIC LIO for the Latvian gas market, but to ensure the uniqueness of "X" type EIC, starting from April 2024, AS “Augstsprieguma tīkls” issues "X" type EIC to both electricity and natural gas market participants.

The codes issued so far remain unchanged and, as of 1 February 2024, all EICs issued by AS "Augstsprieguma tīkls" can be found on the EIC CIO website.

EIC consists of 16 characters. The first two mean the local issuing authority (the code allocated to JSC "Augstsprieguma tīkls" is 43). The third character means EIC type (see the table  “EIC types”). The fourth to 15th character is a freely allocated combination of letters and numbers and the last character is a control sign.
